AUTOMATIC WATER-DISTRIBUTION CONTROL.

Application filed April 6, 1926. Serial No. 100,122.

My present invention has to do with the automatic distribution orcontrol of water supplied by a ump or from any other source of supply;an itcontemplates the provision of automatic control means possessed ofthe practical advantages hereinafter ascribed to the same.

With the foregoing in mind, the invention in all otf its details will befully understood from the following description and claims when the sameare read in connection with the drawing, accompanying and forming partof thisspecification, in which The figure is a view partly in elevationand partly in vertical section illustrating the automatic control meansconstituting the preferred embodiment of my .invention.

y improvement com arises a conduit- 1 adapted to be connected with apump or with any appropriate source of water supply; and it alsocomprises a conduit 2 designed to be connected with a pneumatic pressuretank, not shown, said tank being designed for the supply of water to adwelling house or the like. At 3 is a conduit designed to lead excesswater to a stock watering tank or to any other desired point ofdischarge. Inthe illustrated embodiment the conduit 3 carries a bracket4:, and on the 30 said bracket 4 is a piston cylinder 5 having seats 6and 7 spaced one above the other and also having a cap 8 at its upperend. The pipe 2 is connected by a pipe arm 9 with the lower end of thepiston cylinder 5, and in the conduit 2 and at a point between the pipearm 9 and the pipe or conduit 1 is arranged a check or non-return valve10 arranged to open toward the right in the figure constituting thedrawing. A cut oil valve 1 I is arranged in the pipe 3 and its turnablobody orplug is provided with a crank 12 connected through a rod 13 withone arm of a lever 14 that is pivoted at 15 on the bracket 4, and isprovided on its opposite arm with an adjustable weight or pea 16, theadjustable positioning of the pea or weight 16 on the lever arm beingpreferably attained by the threading of the pea or weight on the arm asshown at the right of the drawing. An appropriately packed piston 17 isdis posed and movable in the cylinder 5 between the seats 6 and 7therein, and when the said piston 17 is disposed on the seat 6 it willbe noticed that only a portion of the area of the piston will e exposedto the pressure in the conduit 2 in connection with the bethe weightedarm of the lever 14 through the mcdrum of a rod 20. y y

In the practical operation of my improvement it will be understood thatwhen the pneumatic tank alluded to is empty or is lled with air atatmospheric pressure, the piston 17 will rest on the seat 6, and thevalve 11 will be closed. With the parts positioned as stated, the waterfrom the pump is forced pastthe check valve 10 andthrough the conduit 2to the pneumatic pressure tank. This operation continues until theressure in the pneumatic tank becomes suhciently high when the pressureacting against the piston 17 will raise the piston 17 to the seat 7 andwill thereby rock the lever 14: and open the valve 11 whereupon thewater will flow past the valve 11 to a stock watering tank or any otherdesired point of discharge or point at which it is desired to impoundthe water. The pressure against the underside of the piston 17 is alwaysthe same as the pressure present in the pneumatic tank, and whensufficient water is removed from the pneumatic tank the weighted lever14 operates to move the piston 17 downwardly to the seat 6. The saidmovement of the lever 14 under the action of its weight 16 also operatesto close the valve 11 with the result that water will again be suppliedto the pressure tank.

Manifestlv the pressure in the pressure tank alluded to may be readilyregulated by changing the position of the pea or weight 16 on the lever14.

It will be apparent from the foregoing that when the pistonv 17 isdisposed on the seat 6, the area of the piston 17 that is subject to thepressure in the pneumatic tank is reduced to the extent of the area ofthe seat- 6. By virtue of" this. inert-used pressure is applied againstthe piston 17 after it leaves the seat 6. and consequently the piston 17will be moved quickly to the seat 7 and will remain against the saidseat 7 until the pressure in the tank has been reduced to the extent ofseveral pounds.

It will be appreciated from the foregoing that my novel control means isextremely simple and inexpensive in construction, and is susceptible ofready installation. and in practice may he depended upon to operate in areliable manner and this with but little or no attention.

I have specifically describedthe construction and relative arrangementof the parts embraced in the present and preferred enibodirnent of myinvention in order to impart an exact understanding of the saidembodiment. I do not desire, however, to be understood as limitingmyself to the construction and arrangement as illustrated and described,my invention being defined by my appendedclaim Within the scope of whichmodifications'may be made without departure from my invention. Forinstance the cap or partial closure 8 may be of any approved type thatwill permitv the circulation of air between the chamber portion abovethe piston 17 and the atmosphere.

Having described my invention, What I claim and desire to secure byLetters Patent, 1s:

Automatic Water distribution control means comprising a pipe adapted tobe connected With means for supplying Water under. pressure, a turnablecut out valve in said pipe and having a crank, a pipe connected with thefirst named pipe at a point between the source olf supply and the cutell valve, a. non-return valve in said second named pipe and arranged toopen in a. direction away from the first named pipe, a. bracket on andextending laterally from the first named pipe, a piston cylinder carriedby said bracket and disposed at right angles thereto and connected atone end to a pipe in connection with the second named pipe at theopposite side of the non-return valve. with reference to the firstnanied pipe. the second named pipe being adapted to lead water underpressure to a pressure ta k, a piston in said piston cylinder andhaving); a rod extending through the oppmite end thereof, a leverpivotally connected at an intermediate point in its length to the saidbracket and arranged alongside the same. a rod connecting one arm ofsaid lever and the crank of the turnable cut off valve. :1 rodconnecting the other arm of said lever and the piston rod, and a Weightaiiljustable on the last named arm of the lever in the direc' tion ofthe length of the lever.

Tn testimony whereof I atlix my signature.

EARL WALKER.
